A study is made to correlate the electrical and mechanical activity of the smooth muscle of the small bowel. Bioelectrical signal recording from the intestinal serosa (electroenterogram) comprises a slow wave (SW) and spike burst (SB), though only the latter reflects intestinal pressure. The electroenterogram and smooth muscle pressure are simultaneously(More)
OBJECTIVE To investigate the impairment of pulmonary function and complications after laparoscopic compared with open cholecystectomy through an upper midline incision. DESIGN Prospective randomised trial. SETTING Teaching hospital, Spain. SUBJECTS 40 patients, 20 in each group. INTERVENTIONS Clinical examination, spirometry, arterial blood gas(More)
OBJECTIVE To investigate the efficacy of respiratory rehabilitation in preventing postoperative pulmonary complications (PPC) and to define which patients can benefit. DESIGN A randomized clinical trial. SETTING A public hospital. PATIENTS Eighty-one patients who had upper abdominal surgery were distributed into two homogeneous groups: control (n =(More)
Recently, hypoglycemia with endogenous hyperinsulinemia has been described after undergoing bariatric surgery because of morbid obesity. It has been theorized that after a gastric bypass surgery, some trophic factors affecting pancreatic beta cells could emerge. The authors present a case of morbidly obese patient with severe hypoglycemia 3 months after(More)
OBJECTIVE To evaluate the prevalence of gastroesophageal reflux disease (GERD) in severely obese patients and the association between symptoms and objective data of GERD in this population. RESEARCH METHODS AND PROCEDURES A total of 158 consecutive severely obese patients (BMI > or = 40 kg/m(2)) were prospectively evaluated. Symptoms were evaluated by a(More)
Pheochromocytoma occurs in nearly 50% of MEN 2A (multiple endocrine neoplasia, type 2A) cases. Many issues related to this tumor are still the subject of debate: the diagnostic management in patients who have had positive genetic study results (RET mutation), variations related to mutation, the best surgical option, and the real relapse rate during(More)
Intestinal myoelectrical activity (IMA), which determines bowel mechanical activity, is the result of two components: a low-frequency component [slow wave (SW)] that is always present, and a high-frequency component [spike bursts (SB)] which is associated with bowel contractions. Despite of the diagnostic significance of internal recordings of IMA, clinical(More)
An external electroenterogram (EEnG) is the recording of the small bowel myoelectrical signal using contact electrodes placed on the abdominal surface. It is a weak signal affected by possible movements and by the interferences of respiration and, principally, of the cardiac signal. In this paper an adaptive filtering technique was proposed to identify and(More)
Electroenterogram (EEnG) is the myoelectrical signal recorded from small intestine. Due to the relationship between mechanical activity and myoelectrical activity of the intestinal smooth muscle, EEnG could be a solution for quantifying intestinal motility. Motility indexes are traditionally calculated from 1-minute window analysis. However, no prior works(More)
BACKGROUND Laparoscopic approach is widely used in our country. This technique has dramatically improved the outcome after surgery, reducing pain, morbidity, hospital stay, and promoting early patient mobilization. OBJECTIVE This study presents 10 years experience and the first 100 adrenalectomies using laparoscopy performed between 1996 and 2007 in(More)
